If `|veca|=2,|vecb|=7 and (vecaxxvecb)=3hati+2hatj+6hatk` find the angle between `veca and vecb`

If veca and vecb asre two vectors such that |veca|=2, |vecb| = 7 and vecaxxvecb=3hati+6hatk find the angle between veca and vecb

If veca and vecb asre two vectors such that |veca|=2, |vecb| = 7 and vecaxxvecb=3hati+6hatk find the angle between veca and vecb

If veca=hati+2hatj-3hatkand vecb=3hati-hatj+2hatk ,then find the angle between veca+vecb and veca-vecb.

If veca=2hati+3hatj+6hatk and vecb=6hati+3hatj-2hatk , find the angle, between vectors veca and vecb . Also find unit vector perpendicular to both veca and vecb

If a=4hati+2hatj-hatk and vecb=5hati+2hatj-3hatk find the angle between the vectors veca+vecb and veca-vecb

If a=4hati+2hatj-hatk and vecb=5hati+2hatj-3hatk find the angle between the vectors veca+vecb and veca-vecb

If vecA = 2hati + 3hatj + 4hatk and vecB = 3hati - 5hatj + hatk . Find the angle between vecA and vecB .

If vecA=2hati+hatj-hatk. vecB=hati+2hatj+3hatk and vecC=6hati-2hatj-6hatk then the angle between (vecA+vecB) and vecC will be :-

Given , vecA=3hati+2hatj-6hatk and vecB=4hati-3hatj+hatk . What is the angle between vecA and vecB ?

If vecA = hati + 2hatj - hatk , vecB = - hati + hatj - 2hatk , then angle between vecA and vecB is
